An Ionic Liquid-Based Absorption Refrigeration/Air-conditioning System for Increased Fuel Efficiency and Reduced Emissions

This research project is investigating the thermodynamics of a completely novel absorption refrigeration system based upon non-volatile ionic liquids (ILs). Previous work indicates that even with model systems, there is enough heat energy in the coolant or exhaust gas of an automobile to operate the system. Current work is reviewing the regions of operability of the technology ionic liquids with refrigerants. Data will allow better selection of ionic liquids and refrigerant working pairs for an actual vehicle air-conditioning system. A major National Science Foundation (NSF) proposal ($364,047) was submitted in October based in part upon preliminary data obtained from this Transportation Research Institute (TRI) grant.
